Describe the bug
Whenever you long-press on a message or conversation, an Action Bar appears. But the problem is that the bar doesn't follow the custom theme chosen by the user. So, please fix this.

To Reproduce
Steps to reproduce the behavior:

1. Open Fossify Messages app.
2. Long-press on any conversation, then notice the Action Bar.
3. Open any conversation & long-press any message, then notice the Action Bar.

Note: Before following above steps, you should already be using a pure black AMOLED Theme like me.

Expected behavior
Whatever colour user has chosen in "Background Colour" & "Primary Colour" should also get applied to the Action Bar.
