BUG:QA4652 - statsinfo can be null

[omero-qa]

​qa 4652 which is related to ​ticket 9655. To prevent errors like this, we will need to assume that statsinfo can be null everywhere.

Note: this would also be an candidate for inclusion in 4.4.x.

In ​https://github.com/will-moore/openmicroscopy/tree/sprint2-web-bugs handle getStatsInfo() nulls in Blitz Gateway: ​https://github.com/will-moore/openmicroscopy/commit/f13de2a387a5eeaab6f55563867b8edfee487030

@wmoore, would it have been worth it to put a method in place for these actions?

[Will Moore <will@…>]

(In [a6c1dfa45ee5c5519df3a0769f116a004a86c056/ome.git] on branch develop) Blitz handles nulls for getStatsInfo() See #9695

getWindowMin() and getWindowMax() will return None if getStatsInfo() is None

[Will Moore <will@…>]

(In [612797660bab10f6dad2db04b1fbc869afc4c31e/ome.git] on branch develop) Use pixelType when getStatsInfo() is null. See #9695
