Changing packageName ignores Java files other than MainActivity.java

[lambdan]

When using Trapeze to modify a Android project's packageName it only handles the MainActivity.java file. Some projects have other .java files, such as custom plugins. Would be nice if Trapeze would handle those files too!

Relevant function (I think...?):

trapeze/packages/project/src/android/project.ts

Line 145 in fa7378c

* package for the `MainActivity.java` file.
