Fix a number of issues with T9 dialer.

- Fix an ArrayIndexOutOfBoundsException which happened when highlighting
  the last digits of a number and the number had additional characters
  after those digits.
- Fix another potential ArrayIndexOutOfBoundsException due to the
  highlighting code relying on normalNumber being a subset of number,
  which wasn't the case due to number being additionally sent through a
  formatter. Fix that by running the formatter before normalizing.
- Fix number highlighting not working if the number match occured at the
  end of the number.
- Fix number type label & formatting not being updated on locale
  changes.
- Fix T9 search not being triggered when pressing the dial button to
  recall the last dialed number.
