ReflectionException when ViewWatcher enabled and debugbar also running

[willvincent]

• Telescope Version: 2.1.5
• Laravel Version: 6.14.0
• PHP Version: 7.3.7
• Database Driver & Version: sqlite

Description:

Similar to #793

This is still occurring with the latest versions of laravel, telescope and debugbar. If debugbar is active with the events collector enabled, and the ViewWatcher is enabled for telescope not even the default welcome view will render, instead the ReflectionException is thrown

ReflectionFunction::__construct() expects parameter 1 to be string, array given

This is referencing line 124 of telescope's ViewWatcher class.

What is being passed in $variables['listener'] causing it to blow up is:
