skip restoring terminals with missing working directory

[danthe1st]

Since we already have M3 now, this may be better for Eclipse 2026-12 but that's a decision for committers.

With restoring terminals now properly restoring the working directory, it doesn't really make sense to restore terminals pointing to a directory that no longer exists so this PR skips restoring these terminals (see also #2859).

I also used this chance to extract the logic for restoring a single terminal from the stored connection properties into a method for better readability.
