"Cannot read property 'token' of undefined" when using an ability from a character that is not in the encounter tracker

[Rachel/Almarane]

I use the Pathfinder 1 system.

Steps to reproduce :

• Create a monster with any attack
• Put the monster on the scene
• Double-click on the monster's token to open its sheet
• Use one of its attacks
  OR
• Create a monster with any attack
• Put the monster on the scene
• Right click on the monster's token
• Use one of its attacks from its quickbar under the token

Do NOT add the monster to the encounter tracker.

=> On the console, this error is displayed :

Uncaught (in promise) TypeError: Cannot read property 'token' of undefined
    at turnmarker.js:56
    at Function._call (foundry.js:2496)

    at ActorPF.PatchCore.ActorTokenHelpers.updateEmbeddedEntity (patch-core.js:199)
    at ItemPF.update (foundry.js:32513)

This error will also break the attack's calculation if you use the dialogue that appears when you use the attack to change some values.

Expected behaviour : I should be able to use a monster's attack even if it is not in the encounter tracker without breaking my roll's calculation
