* An additional GC and wait are needed since WebKit upgrade to version 12.0
(TEXT-FIELD.testMemoryLeak test started failing sporadically)
* Compare colors by value because the runtime has started
to sometimes return instances with different addresses in memory
* Click next moves the focus to next focusable textfield
Fixes https://github.com/NativeScript/NativeScript/issues/5033
When clicking next arrow on the virtual keyboard we were returning true which means we handled the event so the OS doesn't move the focus to the next item. This PR delete the `return true` when the action is `IME_ACTION_NEXT` so that next focusable item is automatically focued
* Fix IME_ACTION_PREVIOUS to raise returnPress event.
Added unit-test that IME_ACTION_PREVIOUS to raise returnPress event.
Refactored text-field-tests
* enable recycling of nativeView
* backgroundInternal is reset if setting new value leads to background.isEmpty() == true.
* android background.getDefault always return copy of the background. Now all controls that mutate the background can be reset to initial state (e.g. Button & ActionBar)
passing resources to copied background so it respect density.
fix properties initNativeView
* reset padding when backgroundInternal is reset.
