* @page mfs_test_001_007 [1.7] Testing garbage collection by erasing

* <h2>Description</h2>
* The garbage collection procedure is triggered by an erase operation
* and the state of both banks is checked.
*
* <h2>Test Steps</h2>
* - [1.7.1] Filling up the storage by writing records with increasing
* IDs, MFS_NO_ERROR is expected.
* - [1.7.2] Erase records until the flash bank is filled entirely.
* - [1.7.3] Erasing one more record triggers garbage collection,
* MFS_WARN_GC is expected, KS state is checked for correctness after
* the operation.
