Direct call to method is not queued

[GrandSchtroumpf]

How to reproduce :

• A calls method M (that takes time) from B
• call is queued
• B calls method M" from B (direct call, no need to use the engine)
• new call is not queued
  -> Method M" thinks that currentRequest is "A"

Solution : Add some kind of metadata in the engine to differentiate direct call with engine calls.
