[Luca Greco [:rpl] [:luca] [:lgreco]]

As part of the changes to fix the intermittent disabled test tracked by Bug 1483701, we are splitting the test file browser_ext_browserAction_popup_resize.js into two separated test files.

The new test file, named browser_ext_browserAction_popup_resize_bottom.js, is running the "browserAction popup resize tests" strictly related to a browser window positioned in the bottom right of the screen (so that we can check that the browserAction popup is opened upward and it has the expected sizes).

This new browser_ext_browserAction_popup_resize_bottom.js is currently failing in debug builds (consistently when I run it locally on linux) because of some shutdown leaks detected when the test file is exiting, and so in Bug 1483701 this test is going to be marked skip-if = debug.

The goal of this issue is to investigate the shutdown leaks detected and apply the fixes needed.
