Fix/remove unneeded tree lookups on ooi views

[underdarknl]

Changes

Made sure the get_ooi is not overloaded to load a tree of (default) 9 deep.
Only load the shallow tree (depth 1) when we are trying to show the related objects and or findings tables.
Only load the full tree when showing the actual tree pages.

QA notes

Make sure the Findings list, and related objects lists on an object detail page still load.
Make sure the tree views on an object detail page still load and is by default 9 levels deep (but can be changed via the form).
Make sure on the default OOI detail page, octopoes gets only a shallow (depth=1) tree call.

Is this check still needed? the tree uses the self.observed_at property of the view anyway.
