Rules editors: Set/unset on 'rating' invalid

[ownedbycats]

Calibre 5.14* (x64, run from source)

"If the Rating column (is set|is not set)" rules produce an error about it being invalid:

calibre, version 5.14.0
ERROR: Invalid condition: One of the conditions for this rule is invalid: <b>'is not set'</b>

Traceback (most recent call last):
  File "D:\Documents\git\calibre\src\calibre\gui2\preferences\coloring.py", line 662, in validate
  File "D:\Documents\git\calibre\src\calibre\library\coloring.py", line 33, in add_condition
  File "D:\Documents\git\calibre\src\calibre\library\coloring.py", line 100, in apply_condition
  File "D:\Documents\git\calibre\src\calibre\library\coloring.py", line 147, in rating_condition
KeyError: 'is not set'

At the time I originally made the rule the 'set/not set' options were not available so I am unsure whether they are actually meant to appear.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
