git-tag: fix -l switch handling regression.

MadCoder · gitster · commit 78d776a9699c · 2007-12-22T00:05:02.000-08:00
The command itself takes an optional &lt;pattern&gt; argument that
limits the shown tags to the ones that match when in listing
mode that is triggered with '-l' option.  The &lt;pattern&gt; is not
an optional option-argument to '-l'.

With this fix, "git tag -l -n 4 v0.99" works as expected.

It also removes a few bogus tests in t7004.
