imsm: FIX: existing backup file fails unit tests

During normal test execution, backup file is deleted after test execution.
If test is interrupted/broken, backup file can remain for next run.
When backup file exists before unit test run, suits 12 and 13 fails.

To avoid this remove backup file before grow is executed.
