Fixes #3867 .

Description

This PR fixes the _set_default_range issue in class RandKSpaceSpikeNoise.

There are two errors in this function:

1. For numpy based img, np.mean does not have the arg dim (this bug is reported in RandKSpaceSpikeNoise got an unexpected keyword argument 'dim' #3867 , thanks to @mibaumgartner !)
2. the generated intensity range has the same type as img, if img is saved in GPU, error will be raised in the following self.R.uniform manipulation step.

In addition, this PR adds the test case (none intensity_range) for RandKSpaceSpikeNoise, and the test case (none k_intensity) for KSpaceSpikeNoise.
