When selecting substance from sidebar, compound is nulled if appropriate

[cmgrulke]

As a user I want the compound to be nulled out if a substance is read into the substance page that has no compound So that I understand the substance better when browsing chemicals

Acceptance Criteria: When I select a DTXSID from the sidebar on the substance page or arrive on one from a search, the compound displayed always represents the substance that is loaded (including no structure if there is no structure

@cmgrulke I feel like this is the current behavior when using the sidebar tree. Especially now with the "Toggle Sidebar" button not being visible when a Substance is loaded (#119).

Steps to reproduce

• Create & save a new substance without defining a "Structure Type"
• If we open this same new Substance from the "Toggle Sidebar" tree I do not have a compound appear on the page

note Although I did notice that if I open a Substance that has an associated Compound, then change the "Structure Type" to "None" I cannot save that removal of association between that Compound and Substance. The "Save Substance" button is greyed out and the 'Save Compound" button is also gone (when selecting "None").

Steps to recreate similar behavior I was able to get a 'dangling Compound' (like you are describing) while using the Search Bar.

• Load 'Substance A' (that has a compound association) via either Search or Tree
• Search for a 'Substance B' that does not have a compound
• Now I see 'Substance B' 's details and the Compound associated with 'Substance A'

? Would submitting/modifying tickets along these lines be more appropriate ?

• Clearing Substance Form on navigation (Compound is cleared on navigation)
• Clearing Substance Form/Compound before returning SF/C from Search (essentially this ticket)
• Clearing contents of Search Box after executing search bonus ticket
• Saving the removal of a Compound's association with a Substance ("Structure Type" set from a_type to "None") bonus ticket

So anytime a substance is loaded into the substance page, I want the compound that is associated with the substance loaded in as well. I think of this as rather than a clear on navigating away, it needs to be an active load on navigation to the page (and I consider the clicking of a new substance in the sidebar or the search of a substance to be a navigation to a substance page).
