file-conflict-dialog: Fix crash on extensionless filenames
The new filename entry has the automatically suggested part of the name
selected for convenience since 9108b4028b7f476b598bc664079fd6d115801b66
However, the logic for this relies on extensions offsets, causing
crashes when failing to handle the extensionless case, which is common
for folders.
So, improve the logic here to handle extensionless filenames, looking
at their length instead.
