When pasting text in kate (using menu, ctrl+v or middle-mouse-button) , auto completion is triggered. Resulting in part of the text becoming obscured by the popup, making these parts inaccessible for the mouse, and overriding the meaning of the up, down, and enter keys. Auto completion is rarely desired when pasting text. In those rare cases, it can quite well be invoked manually. So by default it should not be triggered upon pasting text.

Reproducible: Always

Steps to Reproduce:
1. Open a new document
2. Write the following lines:
test
tests
3. copy 'test'
4. paste it on a new line
Actual Results:  
Auto completion is triggered and must be closed before the user can continue typing/pasting.

Expected Results:  
Only paste the text. Such that the line below is still visible and clickable, the down button moves the cursor down one line and enter inserts a linebreak.
