Fix for UI issue with floating label of MDCTextInputControllerOutlined

[ekrivenja]

I faced with annoying UI issue with MDCTextInputControllerOutlined. In case of this type of Material Design textfield controller has MaskedTextFieldDelegate with params { primaryMaskFormat = "+7-[000]-[000]-[0000]", autocompleteOnFocus = true}, on first focus floating point doesn't display correctly.
If autocompleteOnFocus=false or mask without leading chars (example [000]-[000]-[0000]), everything works fine.
My suggestion, the issue related to method put(...), it changes the textfield text in wrong moment.
Later execution in main.async{} fixes everything.

Please, consider the code review to put all same code patterns in textFieldDidBeginEditing and maybe textViewDidBeginEditing into main.async{} blocks.

What?..
Right now your argument looks like your implementation is altering UI from a background thread, so you expect our library to defend against this nonsense, am I correct?

I am talking only about Material Design Text fields for iOS compatibility.
The issue is not with UI or non-UI threads, but with chain of UITextFieldDelegate callbacks, probably MDCTextInputControllerOutlined expects, but this expected order brakes method put(...) call inside textFieldDidBeginEditing.
This is just my point of view on this issue.

@ekrivenja, okay.

May I see an example of usage?

I haven't found any references to our library within the Material Design library docs, nor I have found any unusual UITextFieldDelegate calls in their git.
