Support for aliases is missing

[Jimmy89]

The current version (2.0.1) does not support alias names for lambda invocations. I support the "$LATEST" tag and version numbers, but not any other alias e.g. stable. Therefore, if a lambda is called with the stable tag the code thinks a different lambda version must be called as isDifferentTarget is set to true (because the lambda version number is used for comparison instead of the tag). Therefore, it tries to call the lambda again instead of triggering a delay.
