Processor test "01-Services.js" on Part-Two has a typo

[sschaefer-rms]

Line 254 defines the address as 5f4d7702 when it should be have a valid namespace prefix attached to it (5f4d76). Have an invalid namespace will short circuit the test since it has an invalid namespace and never gets to test for valid hex.

Thanks for nothing this issue, @sschaefer-rms! Agreed that https://github.com/hyperledger/education-cryptomoji/blob/master/code/part-two/processor/tests/01-Services.js#L256 may short circuit as per https://github.com/hyperledger/education-cryptomoji/blob/master/code/part-two/processor/services/addressing.js#L71. Let me know if you'd like to submit a fix for this issue yourself, otherwise we'll add it to our backlog!
