Allow tabs.update to be called without a tabID

Reviewed by Timothy Hatcher.

The tabID is an optional argument to tabs.update. We were always attempting to get the value of the optional.

If it isn't passed, then it is meant to fall back to the active tab of the current context, which means:
- If this was called from a popup, then the active tab of the popup's window
- If this was called from the background page, then the active tab of the active window

This required some refactoring to WebExtensionContext::getTab and WebExtensionContext::getCurrentTab to support this,
and some tests were added calling this method without a tab ID from both contexts.
