Abort when rows contain errors

[sideeffect42]

Describe the problem

I'm using ImportBundle version 2.5.0.

When I import timesheet entries from a CSV file and some of them contain errors, the correct rows are imported into Kimai nonetheless.

Describe the solution you'd like

The import should not be committed to the database when any rows contain errors.
If the database transaction is rolled back, I can fix the errors in the CSV file and re-upload it.

Otherwise I either

• need to delete all newly imported timesheet entries from Kimai (manually), or
• find and separate the faulty rows from the CSV to only re-upload those again.
