Team delete action does not flag for associated projects

[ramyaragupathy]

While attempting to delete a team, there was an error message pop-up with no useful insight for the user. Upon investigating the server logs, it was identified that there were projects mapped to the team. However, these projects were not listed in the team page.

During team deletion, if there are projects still mapped to the team, a pop-up message should show a relevant error message for the user and encourage them to remove the association from projects.

It is very confusing when there are no projects listed in the team page and then there is a random error popping up. Always a tech team member have to intervene and confirm that there are still projects related to the team in the backend.

This and #6070 go in tandem.
