Fix treemodelcompleter example

All nodes in the view were at the top level due to a spurious trimmed()
call.

The condition in the indentation calculation was flipped, leading to a
segfault.  Also, the input data does not contain tabs.  Remove the
condition that checks for tabs altogether.

This amends commit 3fede6cb547b783377e833c9b269d4cecfe47e61.
