Comment (by SergeyBiryukov):

 In [changeset:"49046" 49046]:
 {{{
 #!CommitTicketReference repository="" revision="49046"
 Tests: Correct the check for image sizes in some REST API attachments
 controller tests.

 If the sizes data could not be retrieved, the controller returns an empty
 object instead of an array.

 This makes sure that the value is in fact an array before proceeding, and
 outputs a proper message in case of failure, instead of an obscure PHP
 error further in the test.

 Follow-up to [49044].

 See #50913, #51393.
