Fix broken Combat achievment IDs

[nwjgit]

Description:

https://github.com/oldschoolgg/oldschoolbot/pull/6095 removed a duplicated CA but some users already completed and have that id stored in completed_ca_task_ids. This PR aims to correct that without manipulating the db.

Changes:

• Create a new array with all the broken CA id
  • Currentley only one 1135
• filter these out from completedTaskIDs for use in displaying ca information to the user.

  Other checks:

• [X] I have tested all my changes thoroughly.

Visual of the current bug: 506/505 this PR will filter out the broken CA to properly display 505/505.

I've just now removed this task from everyone in the database, so this should no longer be needed.
