monster walkback pr causing issues

[ghost]

Before creating an issue, please ensure:

• This is a bug in the software that resides in this repository, and not a
  support matter (use https://otland.net/forums/support.16/ for support)
• This issue is reproducible without changes to the C++ code in this repository

Steps to reproduce (include any configuration/script required to reproduce)

1. go -1 with normal character, wait a second for mobs to notice you then rope yourself
2. have gm wait on -1 to see what happens
3. yes this was tested with both walkToSpawnRadius enabled / disabled

Actual behaviour

the monsters will keep walking towards the rope spot even tho normal character is not there (i thought the pr was about walking back and not surrounding the spot) regardless its a bug

Expected behaviour

before #3604 they stopped walking when player left -1

it was better before, but it was also not correct since Monster::canSee() needs an update

i don't know exactly how it should work on all floors in this version but so far i have seen on Rl that they walk if you are on floor 0 and they are on +1 and +2

aswell will walk if you are floor 0 and they are -1

#3612

[marmichalski]

This should be resolved by #3612, since it marks monster as idle immediately now.
