Extend default script detection in `@Sql` to account for execution phase [SPR-13322]

[spring-projects-issues]

Robert Thaler opened SPR-13322 and commented

Status Quo

We often need to prepare data before a specific test and clean up this data after the test. Therefore we use two distinct scripts assigned to the test's ExecutionPhase.

Proposal

Appending a suffix such as _before or _after to the default script name would allow one to use default detection with different scripts for preparation and cleanup.

Deliverables

1. Default script detection should take the ExecutionPhase into account.
