Remove incorrect menu display fallback (#361)

* Remove incorrect fallback case. We can always just default to mouse location

* Remove accidental change to an android patches file (whitespace)

* whitespace fix

* revert change

* remove event code and just show the menu under the anchorview everytime we have an anchorview

* Update RCTActionSheetManager.m

* Update RCTActionSheetManager.m

* cleanup minor improvments and patch revert

* refactoring means we don't need a view var anymore
