Whiteboard tag parsing can lead to the wrong action being selected to process a bug

[grahamalama]

Scenario:

There are two action configurations:

- whiteboard_tag: foo
  ...
- whiteboard_tag: bar
  ...

JBI receives a webhook payload with a whiteboard string that includes "[foo-bar]"

Does that refer to:

• the whiteboard tag foo with metadata bar?
  or
• the whiteboard tag bar with metadata foo?

In cases like this, the order of the actions in the configuration will matter. The foo action will be selected with the current configuration, but if we were to flip the order of the actions, the bar action would be selected. Situations like these may lead to issues being created in the wrong projects.
