Attachment: Bug 1388342 - Ensure browser_tabstrip_overflow_underflow_reflows.js works for both the e10s and non-e10s case.

We hit the _adjustFocusAfterTabSwitch function in both the e10s and non-e10s cases, but through
different code paths. This makes the expected stack less specific to account for both cases.
