test: Fix deser issue in create_block

Browse source 
Without the fix a hex-string can not be parsed:

File "./test/functional/test_framework/blocktools.py", line 82, in create_block
    txo.deserialize(io.BytesIO(tx))
TypeError: a bytes-like object is required, not 'str'

Also, remove io import and repace it with our FromHex() helper
