Before this commit, if the user has read only access to a record:
- User could see 'Add Followers' button, which raised AccessError
- User could see edit and remove icons but performing these actions
for followers other than one related to logged in user, it also
raised AccessError.
With this commit, we are restricting it based on the user rights, if
the user has read only access to a record:
- 'Add Followers', subtype edition(pencil icon) and follwer removal
buttons will be visible only for the follower related to logged in
user, not for others. This way we can avoid the unexpected
AccessErrors.
Note that if user is having write access for the record, nothing
changes.
