LocalDiskRepositoryTestCase#createRepository: Default auto-close to false

Since 8ed59c5 ("Make TestRepository AutoCloseable", Jan 11, 2019) the
TestRepository class is auto-closeable, but instantiations of it were
not converted to use try-with-resource.

Converting to try-with-resource results, in several cases, in the
repository being closed twice because LocalDiskRepositoryTestCase has
logic to close created repositories in the tearDown method. This results
in several tests emitting a warning to the console:

  close() called when useCnt is already zero

Change the default behavior of the createRepository method to not use
the auto-close logic in LocalDiskRepositoryTestCase, so that thy will
instead be closed (only once) using the AutoCloseable implementation.

Deprecate the method that has the autoClose parameter.
