Can't create mRNA plate with External RNA or Stratagene

Description

If there is at least one location with either the "External" RNA item or "Stratagene" a NullPointerException is thrown when registering the plate.

 java.lang.NullPointerException 
  at net.sf.basedb.reggie.servlet.MRnaServlet.doPost(MRnaServlet.java:563) 
  at javax.servlet.http.HttpServlet.service(HttpServlet.java:648) 
  at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) 
....

After investigating this it seems like this was broken by [3302] which changed the way quantities was calculated in order to support NeoPrep that sometimes required a "large mix" due to small volumes.

As a side-effect the quantity was never set on "External RNA" or "Stratagene".

(In [4374]) Fixes #948: Can't create mRNA plate with External RNA or Stratagene

If no "usedQuantity" has been set before registration on an RNA the current quantities are used (taken from the selected protocol).

A second problem with remaining quantity calculations and pre-normalized RNA also needed to be fixed. The "Stratagene" and "External RNA" items don't have any registered remaining quantity which caused another NullPointerException.
