boost/reblog nulls out the favourited property (and vica versa) in returned status

[technicat]

Starting with a status not favourited or reblogged

"id" : "690329321475336860",
"reblogs_count" : 1,
"favourited" : false,
"reblogged" : false,

Favouriting it returns the expected result

"id" : "690329321475336860",
  "reblogs_count" : 1,
  "favourited" : true,
  "reblogged" : false,

But then reblogging it returns a status with reblogged set but favourited nulled out

"id" : "690329321475336860",
  "reblogs_count" : 1,
  "favourited" : null,
  "reblogged" : true,

I believe this happens in the other order, too - favouriting after reblogging returns a nulled out reblog field.

Retrieving the status again via statuses shows the correct values for both properties (which is my current workaround, refresh the post after each favourite and reblog).

  "id" : "690329321475336860",
  "reblogs_count" : 1,
  "favourited" : true,
  "reblogged" : true,
