revset: use try-except instead of if-else because of perf

For wdir(), we now raises an exception which will be raised when wdir() will be
passed, so catching that exception is better checking for wdir() using if-else.

  $ hg init
  $ echo a > a
  $ hg commit -A -ma
  adding a

  $ echo b >> a

  2 other heads for branch "default"

Should fail because > 2 heads:

Test for issue2043: ensure that 'merge -P' shows ancestors of 6 that
are not ancestors of 7, regardless of where their common ancestors are.

Merge preview not affected by common ancestor:
