Restore file test/myclirc from repository after test writes

[rolandwalker]

Description

This test

mycli/test/test_special_iocommands.py

Lines 83 to 90 in 4517f49

	@dbtest
	def test_favorite_query():
	with db_connection().cursor() as cur:
	query = u'select "✔"'
	mycli.packages.special.execute(cur, u'\\fs check {0}'.format(query))
	assert next(mycli.packages.special.execute(
	cur, u'\\f check'))[0] == "> " + query

writes to test/myclirc, leaving it "modified" in the worktree, according to git status, after the test suite is run.

We can simply check out a fresh copy of the file after running the tests. If the git executable is not present, or the code is not in a checked-out repository, the command will silently fail.
