tests: add testcase for 208fc9ad6a48 to test-alias.t

The testsuite lacks a testcase for the bug introduced in 208fc9ad6a48.

This patch amends 301d7626e0ff (which fixed 208fc9ad6a48) by adding a
testcase for that bug.

With 208fc9ad6a48, test-alias.t (as modified by this patch) fails
with "hg tglog: invalid arguments".
