Changed signature in preparation for unit testing

Split out method `restoreChars()` so it can be run in unit test

* also adjust CountSurrogatePairsTest

fix[android]: fix cursor after insert

* Make performLeftDeletions private
* Add try catch block to guard against out of bounds errors

This does a better job of updating the cursor so the next character gets correctly inserted

fix: Temporarily disable dictionary when entering password field

Per review comment, separate getter and setter of state variable.
Also renamed mayProtect typos to mayPredict
