Safe point triggers on blast+ search

Scenario to reproduce:

1. Select "Tools" -> "BLAST" -> "FormatDB..." item in the main menu.
2. Set "data/samples/FASTA/human_T1.fa" as input file, set any valid output path, accept the dialog.
3. Select "Tools" -> "BLAST" -> "BLAST+ Search..." item in the main menu.
4. Set "data/samples/FASTA/human_T1.fa" as input file, set the database that you created before, accept the dialog.
   Current state: SAFE_POINT triggers, there is an error in the log: "SQL: error: SQLite: Error finalizing statement: Error querying database: foreign key constraint failed in query: INSERT INTO ObjectRelation (object, reference, role) VALUES(?1, ?2, ?3)
   Trying to recover from error: Unexpected query result code: 19 (foreign key constraint failed) at src/models/GObject.cpp:188"

The issue requires GUI tests.
