Fix 2nd bug introduced in Ic13a4bfc99596f1e2fc6a280aafec075004bcd5c.

Didn't run the tests after the requested nit was addressed; that
tightening/fix introduced fallout additionally in GetGerritPatchInfo.

Obvious enough fix, although should've been caught; affected usage
was for internal querying.

BUG=chromium-os:29546
TEST=gerrit_helper_unittest.py # Covers this.
