Issue/Bug description:
Attempting to copy text from open file contents and paste it into find dialog has unexpected results, as different text ends up getting pasted.

Steps to reproduce:

1. Open some other editor/terminal/browser (anything that text can be copied/pasted fromto).
2. Open any file in cosmic-edit.
3. Verify copy-paste functionality in the edit areas, as follows:
   a) Copy text1 from cosmic-edit, verify that it can be pasted to other application.
   b) Copy text1 from cosmic-edit, verify that it can be pasted in a different area of currently opened cosmic-edit file.
   c) Copy text2 from other application, verify that it can be pasted to currently opened cosmic-edit file.
4. Verify copy-paste functionality between edit are a Find/Replace dialog
   a) Copy text1 from cosmic-edit
   b) Open Find/Replace dialog (CtrlF/H or menu all behave the same)
   c) Set focus to either find or replace text box, then Ctrl-V to paste
   d) BUG - Notice that text2 is pasted (from step 3c) instead of text1 (from step 4a).

Expected behavior:
Text1 gets pasted, as it was the last thing copied from the open file.

Other notes:

There is actually no way that I have found to copy text from the edit area and paste it into the find/replace dialog. This is obviously very annoying, since most of the time I am trying to find instances of something in the current file.
