f2prateek Fix usage of String.split
The build currently fails with this error:

/Users/prateek/dev/src/github.com/f2prateek/rx-preferences/rx-preferences/src/test/java/com/f2prateek/rx/preferences2/PointPreferenceConverter.java:7: warning: [StringSplitter] String.split(String) has surprising behavior
    String[] parts = serialized.split(",");
    (see http://errorprone.info/bugpattern/StringSplitter)
  Did you mean 'String[] parts = serialized.split(",", -1);'?
error: warnings found and -Werror specified
1 error

This fixes the usage of String.split as recommended by http://errorprone.info/bugpattern/StringSplitter.
