Improper use of Application
ID plugin causing unbalanced NSIS stack

|Details | Review|
In the function UpdateShortcutAppModelIDs  we make 5 calls to ApplicationID::Set where we pass it only two parameters, but it expects a third (or an empty stack otherwise). The result is an extra item being popped off the NSIS stack. This was originally discussed and patched in bug 425167, but this is a different root cause from the issue that bug was originally filed for.  https://searchfox.org/mozilla-central/rev/3fa761ade83ed0b8ab463acb057c2cf0b104689e/toolkit/mozapps/installer/windows/nsis/common.nsh#6999
In theory, the third parameter (dualMode) to the NSIS ApplicationID plugin's Set function is optional, but the plugin assumes that either it's there or there's nothing else on the NSIS stack, so it pops three items from the stack unconditionally. This means that supplying only two parameters results in one item silently being dropped from the NSIS stack. Fortunately this one function is the only place where we were doing that, so it only became a problem if there were an awful lot of shortcuts (around 7) to the same installation.
