Preserve old password when handling SET_NEW_PASSWORD.
Currently the only way mUserPassword can be set is when it comes
from onActivityResult. This way when the user chooses "Continue
without Pixel Imprint", and we switch ChooseLockGeneric->InternalActivity,
mUserPassword becomes null (it is not preserved in intent extras).
And then this null is used in getLockPasswordIntent which causes the issue.
Another issues is that when the user chooses to use fingerprint,
mHasChallenge is set to true and password is not forwarded to
ChooseLock(Password|Pattern). I changed the intent builders so that both
old password and challenge can be sent at the same time, so the password
is not lost when fingerprint is set.
