process.GetTargets: error with no destination found is misleading
Created originally on Bitbucket by cdevienne (Christophe de Vienne)
When no destination actor is found, the error message is:
2019-01-18T10:06:12+01:00 xbusd[26287]: 2019/01/18 10:06:12 Caught panic: can only handle a single destination
This is misleading and should be more helpful.
