RTL issues with multiCopter

[santiago3dr]

If engaging RTL multiple times in the same flight, the second+ instance of RTL goes towards a previously set path by the first RTL engagement.
Couple examples:

I think we need to fix this pre-release

I cant reproduce this in SITL, also i don't see this behavior in the logs posted but they are a bit hard to read.

@Stifael Could you have a look?

I am also not able to reproduce it. so far I looked at the first log, and it seems that navigator sends out the correct setpoints.

@santiago3dr Could you please try to reproduce this?

reproduced with pixracer (V4) running current master b21af47

of the 3 instances rtl was engaged, 1 and 2 took direct path home while the third attempt headed towards a path previously set by a prior instance of rtl

@santiago3dr thanks. it is a much simpler log and I think I just found a pattern

[Stifael]

I can reproduce it now
