mannol b47191608b Fix issue with composing text not being cleared on some Android devices (#18859 )

Summary:
Clearing the android TextInput text programmatically (i.e. calling: this.textInputRef.clear()) does not clear the previously composing text, if enabled, causing inconveniences when such behaviour is desired (i.e. chat input box, where you constantly have to clear the input after sending a message). Instead, the currently observed behaviour is that, after a new text is entered (usually as soon as the first letter), the previously composing text reappears making the input unusable.

The effect is only observable on some devices, for example, we observed it on Samsung S6 devices using both Android 6 and 7, and several LG devices running Android 6.

This issue is only present when clearing the text; setting text to some other value does not produce the same effect.
