fix(context): Ensure resource set paths are made absolute

Resolving of files (for `insertFile` and `insertTemplate`) should
always be relative to the resource set location, the previous
behaviour was considered a bug.

This is fixed by ensuring that resource set paths are absolute at
context loading time.
