Error in QC join function

In the current version of bio_hansel, we get an error on Galaxy as follows:

TypeError: sequence item 0: expected str instance, int found

This is because in qc/checks.py at line: 92:
; '.join(conflicting_tiles['refposition'].tolist()) will try to join 1 conflicting tile's refposition which is being interpreted as an integer.

Should change this to:
'; '.join(conflicting_tiles['refposition'].astype(str).tolist())

Thanks for catching this @hellothisisMatt ! I'll cut a new release with this bug fixed. Added a test to ensure it doesn't occur again.
