exchange: fix locking to actually be scoped

The previous code was taking locks before entering with statements, so
exception before the with statement would not release the lock (except for
garbage collection).

We need to move to a try except here because the logic is more complicated.

  $ rm -rf a
  $ hg init a
  $ cd a
  $ echo a > a
  $ hg ci -Am0
  adding a
  $ hg tag t1 # 1
  $ hg tag --remove t1 # 2

  $ hg co 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg tag -f -r0 t1
  $ hg tags
  tip                                3:a49829c4fc11
  t1                                 0:f7b1eb17ad24

Ensure that the username access fails gracefully if assumptions about the
environment made by python do not hold.

#if windows
  >>> import os
  >>> from mercurial import util
  >>> os.environ.pop('LOGNAME', None) and None
  >>> os.environ.pop('USER', None) and None
  >>> os.environ.pop('LNAME', None) and None
  >>> os.environ.pop('USERNAME', None) and None
  >>> print(util.username())
  None
#endif
