Prevent phylorefs from being modified by being opened by the Specifier component

[gaurav]

WIP: I could try to create a complicated normalization method here in Klados, but the right way to do this is probably to do this piece-by-piece in phyx.js -- so that the PhyxWrapper tells the PhylogenyWrapper and PhylorefWrapper to wrap their respective objects, and so on down the line. This is being tracked there as phyloref/phyx.js#134.

Should fix #263.

• Make collapsed form non-editable and replace the "Expand" button with an "Expand/Edit" button or two buttons that do the same thing. Note that the edit button could be an icon rather than a full button.
• Change the logic: don't update the verbatim specifier, but do update the binomial/genus/specific epithet/infraspecific epithet if any of them change. That should get rid of this issue.
• If the file is missing details (e.g. no infraspecific epithet), which the tool fills in when you load the file.
  • We could highlight the specific modified field to indicate to the user that something here has changed.
