Safeguard remove cap from collisions with roles

[BhargavBhandari90]

Fixes #98

---

Let's start with this:

---

• Added Role ExMember and capability exmember
• Now when we try to run comman: wp user remove-cap 1 exmember
• It will have error ( see the screenshot below ): There is a role similar to 'exmember' capability. Use wp user remove-role instead.

Thanks for starting this!

The example you mentioned would make for a good Behat test :-) Would you be up for adding one?

[BhargavBhandari90]

Sure @swissspidy I'll add the Behat test. Thank you.

[BhargavBhandari90]

@swissspidy added behat test. Let me know if this works.

The original suggestion in #98 (comment) was to add a --force flag to ignore the error and still remove the cap, maintaining existing behavior

[BhargavBhandari90]

@swissspidy I've added force flag. Let me know if that works. Thanks
