Fix: crash using tab in attribute search

Browse Source 
The crash happens when hitting tab while using attribute search in the Geometry
Nodes modifier. This triggers some auto-completion code (which doesn't work here
currently, but that's potentially a separate problem). However, the
auto-completion code did not handle the case when the string that's
auto-completed does not have a maximum length, i.e. it is dynamic.

This patch adds some handling for the case when the auto-completed string
storage has a dynamic size.
