templater: handle None returned from templatedir()

My recent 91aa9bba3dc9 (templater: make templatepaths() return a
single path, or None, 2020-07-21) didn't account for the fact that
`templatedir()` returns `None` in frozen binaries. That is ironic,
since the reason I'm working on this is to add support for built-in
mapfiles in frozen binaries. This patch updates the callers to handle
the `None` case. It's somewhat ugly, but I will have to revisit this
soon anyway, since my goal is to make all callers handle that case by
trying to read the map file using the resources API instead.

== New Features ==

 * The amend extension supports the `--currentuser` argument.

 * The amend extension supports the `--close-branch` argument.

 * The amend extension supports the `--secret` argument.

 * The uncommit extension supports the `rewrite.update-timestamp` config option.

== New Experimental Features ==


== Bug Fixes  ==


== Backwards Compatibility Changes ==

 * A shell that supports `$(command)`` syntax for command substitution is now
   required for running the test suite. The test runner normally uses
   `sh`, so if that is a shell that doesn't support `$(command)` syntax,
   you can override it by setting `$HGTEST_SHELL` or by passing it to
   `run-tests.py --shell <shell>`.

 * The (experimental) narrow extension's wire protocol changed. If
   you're using it, you'll need to make sure to upgrade server and
   client at the same time.

== Internal API Changes ==
