Don't reload on initialize. Fixes #87

[jcoyne]

This supersedes #114

This is kind of wonky when you attempt to interact with the resource directly.

if you do something like:

source.insert [subject, predicate, uri]
source.get_relation :foo

Because the insert doesn't mark loaded?, the get_relation ends up triggering a reload and the first insert is lost.

Sorry, should've commented directly here. See respective comment on #87.

FWIW, I don't like the idea of having to manage persistence state (@persisting, @loaded, etc) within an RDFSource. IMO this is the job of a chosen PersistenceStrategy now that we have it.

Also to clarify now that I've had a closer look, this is just for behaviour against v0.7.x, i.e. not to be carried forward into develop, correct?

[jcoyne]

Right, this is just 0.7.x

[mjsuhonos]

Right, sorry. Never mind me, then.
