[bugfix][DbManager] 14110 - Error fetching layer indexes with recent sqlite version

Fixes #14110

The method `getTableIndexes`, situated in line 371 of the file `db_manager/db_plugins/spatialite/connector.py`,
expected to get 3 fields from the sqlite method `PRAGMA index_list` .
In recent versions of SQLite, since 3.8.9, though, this method now returns 5 fields.
This commit fixes this issue by checking the length of columns returned by the method.
