Sanity check input queue name length

[alyandon]

This fixes a case where sending a command like "get /peek" causes the creation of a queue with an invalid name. This invalid queue name is persisted to the leveldb data store and subsequently prevents siberite from starting successfully.

Fixed an additional unit test that is no longer working in Go. The other CI build errors look unrelated to this change and all tests now pass on a clean checkout for me.

../../onsi/gomega/gomega_dsl.go:312: syntax error: unexpected = in type declaration

That looks like the result of a backwards incompatible change made in gomega?
