test-merge-tool: Make sure no hgmerge can be found in $PATH

The merge tool selecting algorithm is hardcoded to look for hgmerge in $PATH
before it falls back to use internal merge. This fixes the test for this
fallback to be tolerant to existing hgmerges.

# this is hack to make sure no escape characters are inserted into the output

if 'TERM' in os.environ:
    del os.environ['TERM']
