Context: Pressing middle mouse bound to an actionbar does not always fire the correct macro.

Expected: Pressing the middle mouse actionbar binding should execute the appropriate macro.

Observed: Error message states spell not found.

Repro steps:
1. Create a macro using a spell, for example Cleric Symbol of the Torch and bind the middle mouse press to an actionbar and drag the macro to it.
2. Press the middle mouse and the macro should work as expected.
3. Change souls or character
4. Create another macro and repeat step 1 with a different spell.
5. Join a group or raid and occasionally the spell will not work and an error will occur looking for the spell from step 1 (other soul or character).
