Canvas.text: fix segfault with ellipsis cases

The specific handling for (0.0 <= ellip < 1) doesn't support multi-line cases.
One of the main reasons is that we haven't had the chance to define the wanted
behavior for multi-line.
This is a temporary hack to fix a segfault. The behavior is still undefined,
though.

Fixes T3885.
