phabricator: properly encode boolean types in the request body

I tripped over this playing with `hg debugcallconduit` to query for valid
reviewers.  If the JSON on stdin is written as 'True' or 'False', python
complains it isn't valid JSON.  If it's written as 'true' or 'false', it made it
to the server, but got kicked back with this:

    abort: Conduit Error (ERR-CONDUIT-CORE): Error while reading "isBot":
           Expected boolean (true or false), got something else.

The test isn't really relevant here (the code can be reverted, and it will
pass), but this gives us coverage for the debug command.

Implicit merge with test branch as parent:

  (run 'hg heads' to see all heads)

Implicit merge with default branch as parent:

  $ hg merge

3 branch heads, explicit merge required:

  $ hg merge 2

  (branch merge, don't forget to commit)
  $ hg ci -m merge

2 branch heads, implicit merge works:

We need special handling for repositories with no "default" branch because
"null" revision belongs to non-existent "default" branch.

  $ hg init nodefault
  $ cd nodefault
  $ hg branch -q foo
  $ touch 0
  $ hg ci -Aqm0
  $ touch 1
  $ hg ci -Aqm1
  $ hg update -qr0
  $ hg branch -q bar
  $ touch 2
  $ hg ci -Aqm2
  $ hg update -qr0
  $ hg branch -q baz
  $ touch 3
  $ hg ci -Aqm3
  $ hg ci --close-branch -m 'close baz'
  $ hg update -q null
  $ hg log -GT'{rev} {branch}\n'
  _  4 baz
  |
  o  3 baz
  |
  | o  2 bar
  |/
  | o  1 foo
  |/
  o  0 foo
  

 a) updating from "null" should bring us to the tip-most branch head as
 there is no "default" branch:

  $ hg update -q null
  $ hg id -bn
  -1 default
  $ hg update
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg id -bn
  2 bar

 b) but if we are at uncommitted "default" branch, we should stick to the
 current revision:

  $ hg update -q 0
  $ hg branch default
  marked working directory as branch default
  $ hg id -bn
  0 default
  $ hg update
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg id -bn
  0 default

 c) also, if we have uncommitted branch at "null", we should stick to it:

  $ hg update -q null
  $ hg branch new
  marked working directory as branch new
  $ hg id -bn
  -1 new
  $ hg update
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg id -bn
  -1 new

  $ cd ..

We expect that update --clean discard changes in working directory,
and updates to the head of parent branch.

  $ hg init updatebareclean
  $ cd updatebareclean
  $ hg update --clean
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
