Instead of converting hash into JSON inside
issuable_initial_data method, return hash and convert
to JSON later. This allows us to easily extend basic
issuable data with resource specific values. For example
for Epic these data should include also labels, so we can then
do something like:
issuable_initial_data(@epic).merge(labels: @epic.labels).to_json

These are obscuring the real error, which is confusing for everyone.
