fix(kitsu-core): Merge meta keys to preserve data (#853)
Previously only the meta from the resource identifier object was preserved, while the resource object meta was discarded, resulting in some cases where meta would be set to undefined. The meta keys are now merged instead of picked between, preserving the largest amount of data possible. Co-authored-by: James Harris <[email protected]>
