Tooltip: Preserve the title attribute after disabling twice

[mwiencek]

Fixes #9719

[mwiencek]

The condition that decides whether to move the title attribute to ui-tooltip-title is line 129 - it simply checks whether a title attribute exists. Changing the title to an empty string does not remove the attribute, so calling disable twice will save the empty string to ui-tooltip-title on the second call.

Added a test which demonstrates the problem, and fails without the patch applied.
