BUG: Original metadata display stalls

[rkferguson]

Tested with OMERO.insight-4.4.8-47-0c111ca-ice33-b238-mac on howe using .dv and canon files.

The first time you click on the Original metadata tag it starts to open then stalls with "Loading metadata" with a stationary progress spinner. If you then click on it again, you see a flash of the download arrow just before the tab closes and then when it opens it displays fine immediately. On subsequent opening, there is a few seconds delay at the "Loading metadata" stage, but the download arrow and metadata then appear as expected. If the display of metadata is stalled, then clicking on and shifting focus to the import window triggers the display in the main window. Even shifting focus to another app window triggers display after stalling.

It seems that the first time after import that the metadata is loaded, it is being fetched, but the display is not being triggered until another event takes place. The display is then done, and subsequent viewing of the metadata does not suffer from this delay.

It is interesting that this stalling does not take place with data where the original file has been archived at import. This may help give an idea of where the problem is.

When metadata is displayed it appears to be as expected.
