Revert "iOS: Treat the initial Info.plist string as a mustache template and use the project name to initialize the bundle name and identifier"

This reverts commit dd4361bc.

We still use the hard-coded name in a number of places, including
launching the app on the iOS simulator.

Enforce that we get a final move to the pointer up location

`flutter start` initializes the Xcode project if the user has not already done so.

Previously we asserted that we got a pointer move to the location where the
pointer up occured, but not all sources of pointer packets respect that
invariant. Specifically, on the iOS simulator, of you drag outside the window,
you'll get a stream of pointers that violates that invariant.

This patch teaches the converter to insert a PointerMoveEvent to move the
pointer to the location where the up occurs, repairing the invariant.
