QTabBar: smaller minimumSizeHint in ElideMode, and unit-test.

When a tabbar had a large number of tabs with short text
(5 to 7 characters), no eliding would happen, the window would keep
growing until it became wider than the desktop. This commit therefore
reduces the minimumSizeHint using more aggressive eliding when eliding
is enabled.
Also, at some point I had doubts about whether minimumSizeHint took
eliding into consideration at all, so I also added a unit-test for
minimumSizeHint and sizeHint of tabbars, in various modes.
