Wrong ID references in Test Suite and failing test suite

[abs51295]

1. Wrong ID references R.id.next and R.id.done in the following file which should be corrected to R.id.btn_next and R.id.btn_done according to this and this.

2. Although EditText in this file can accept only Alphabetic characters and white spaces, the test described here does not respect the constraints and should be changed in order for it to pass.

If this is an issue, let me know I am ready to work on it. Thanks.

@sandarumk Please review my PR #407 so that I can add tests for run time permissions as well.
