Title: Adapting rest to new DAO\'s - CAF-302

Improved 5 DAO's to make a single query when updating a timestamp column in the DB.
They changed from doing:
```
a = "select SYS_EXTRACT_UTC(SYSTIMESTAMP) from dual"
sql = "UPDATE tasks SET tm_end_injection = :a"
```
to:
```
sql = "UPDATE tasks SET tm_end_injection = SYS_EXTRACT_UTC(SYSTIMESTAMP)"
```
