Fix crash when searching while no tab is selected

Query guarded the upper bound of SelectedTab but not the lower. SelectedTab is
bound two-way to the tab selector's SelectedIndex, which is -1 whenever there is
no selection, so Tabs[SelectedTab] threw ArgumentOutOfRangeException if the tabs
were repopulated while the user was still typing.

Reported by crash telemetry on 12.9.0.0.
