Re-insert linebreak in dwarf_stack_trace_test
Re-insert linebreak in dwarf_stack_trace_test

This file was auto-formatted 2 months ago.
This - among other things - removed a linebreak which shifted linenumbers
by one, but didn't update the expected linenumbers from a throw accordingly.
Somehow the testserver has claimed that this has passed until now.
I have no idea how that happened.

This CL re-introduces the linebreak by inserting a comment,
which (currently) forces dartfmt to have the wanted linebreak.
