4373: PWA: Don't use white nav bar below Oreo r=rocketsroger a=NotWoods

Below Oreo, white navigation bars just look like a giant white rectangle since we can't darken the button colors.

A quick fix that makes it feel less laggy. I did some measurements on various devices. See issue #4353.

4372: Rename isPWA to isInstallable r=Amejia481 a=NotWoods

I'm worried about confusion between a tab that can be installed as a web app vs a session opened as a PWA inside `ExternalAppBrowserFragment`. This hasn't been integrated into Fenix just yet so let's rename it.

4358: Closes #4348: Empty toolbar after switching from custom tab to browser r=pocmo a=csadilek

Pretty much exactly as described in https://github.com/mozilla-mobile/android-components/issues/4348#issuecomment-529508578

. We need to update our store to move the tab from the custom tab list to the regular tab list. I decided to re-use our existing events (Remove, Add) instead of introducing a new one, as it's technically two different reducers having to handle it.

I've verified that this fixes the issues in Fenix (and r-b).

4360: Closes #4350: Allow for a missing `action` param in FxA auth flows r=jonalmeida a=grigoryk

It's possible that `action` parameter may be missing. This patch adds handling for that case,
and tests for the interceptor (which were missing entirely) that cover all combinations.
