Screebl Beta won't survive screen lock, when main app closed from task manager

[Marián Hello]

Hi, I find Screebl amazing app, but there is one thing that bothers me and  I don't know if it is bug or feature.

HW: LG Nexus 4

Android Version: 4.2.2

Overview: Screebl Beta closes or crashes on next screen lock, when Screeble was closed from task manager.

This doesn't happen when not closed from task manager.

Steps to reproduce:

1. Open Screebl.

2. In Screebl, enable Screebl checkbox.

3. Force close Screebl from android task manager. Icon of Screeble is still visible and Screeble is still working.

4. Put the phone in a horizontal position and wait for screen lock

5. Unlock phone.

6. Screebl is not running (no icon)
