Inconsistent int grain key formatting

[oleggolovkov]

I have 2 grains implementing IGrainWithIntegerKey, something goes wrong and in logs I see (trimmed) this:
Status Response [S10.2.1.77:8952:80242663 somefirstgrain/37] ->[S10.2.1.77:8952:80242663 somesecondgrain/55] IsExecuting: True, IsWaiting: False, Diagnostics:...., both these grains are using the same 55 ID and in one case (source) it is in hex format - 37 and in the other case (target) it is in decimal format - 55
