Payload error on some searches

[kltm]

From David:
I searched on Lrp4 and selected the mouse gene. Amigo2 reported 29
results. When I page to results 11-20, the table is blank even though it
says "showing 11-20"

To reproduce:
Go to Search, type "Lrp4", select MGI Source filter, select "Lrp4" gp link, page through the pinned annotations.

Yet 21-29 seems to work fine. Taking a look, it seems there is an error
in the JSON parsing of the payload coming back from the server. This
likely means that either the loader is loading something wrong or there
is some serious input problem (although a quick scan of the JSON didn't
show any obvious problem in annotation_extension_json).

A little poking has turned up that it chokes on: "transports_or_maintains_localization_of", which should not be there, it should be a JSON object to render correctly. This puts the root bug up in owltools. However, it would be nice to not have the crashes and actually display errors, so I've made it a little more robust down here so that errors get passed through with a "?" tagged onto the end.

I'll deal with the owltools/loader issue separately.

Stepping back from showstopper since AmiGO has a workaround for the upstream error. However, now that clients are contacting GOlr directly, it would be good to get the to bottom of this issue.

there is the line:

"annotation_extension_json":["regulates_o_has_agent"],

which is obviously not a healthy JSON relation. Compare to:

"annotation_extension_json":["{\"relationship\": {\"relation\": [{\"id\": \"BFO:0000066\", \"label\": \"occurs in\"}], \"id\": \"EMAP:5134\", \"label\": \"TS21 dorsal root ganglion\"}}","{\"relationship\": {\"relation\": [{\"id\": \"RO:0002296\", \"label\": \"results in development of\"}], \"id\": \"CL:0000101\", \"label\": \"sensory neuron\"}}"],
