Passing around of the component was used when there were two
independent Notification components. Now that there is only
one Notification component, it is not necessary to pass
around the component.

It was decided along with the mute participant dialog reactification
that these types of warning messages should not be toggleable--that
they should simply always display because there is no undo action.
As such, the component NotificationWithToggle is no longer needed.

* ref(notifications): convert some dialogs to error or warning notifications

- Expand the configurability of the Notification component so warnings
  and errors can be displayed.
- Allow Notification to take in arbitrary text for the body.
- Rename defaultTitleKey to titleKey for consistency with descriptionKey.

* ref(notifications): remove openReportDialog method

openReportDialog is a wrapper around showError that adds
a logger statement. It is being called in one place only
so remove the method and have that one place call logger.

* ref(notifications): UI.showTrackNotWorkingDialog takes a boolean

Change UI.showTrackNotWorkingDialog so it takes a boolean
arguments instead of the entire track. A small refactor so
the method needs to know less.
