ProjectPermissionModificationRequestedEvent not raised when setting default project permission

A ProjectPermissionModificationRequestedEvent is not raised when changing the default permission of a project from "No Access" to something else.

Steps to reproduce

1. Create a project and set the default project permission to "No Access".
2. Add an event listener (e.g. to a plugin) which listens to ProjectPermissionModificationRequestedEvent and logs a message when the listener is triggered.
3. Change the default project permission from "No Access" to something else (e.g. PROJECT_READ).

Expected

A ProjectPermissionModificationRequestedEvent is raised (and a message is logged via the event listener).

Actual

No ProjectPermissionModificationRequestedEvent is raised (and no message is logged via the event listener).

Note changing the default project permission from PROJECT_READ to PROJECT_WRITE or vice versa does raise the ProjectPermissionModificationRequestedEvent. Only changing the permission to or from "No Access" does not raise the event.
