This one's easy. The bracket is only printed if the total vertical
extent of the system exceeds the value of the collapse-height
property, so if you add a setting
   \override Score.SystemStartBracket #'collapse-height = #1.0
you will get the bracket for all systems with multiple staves.

This looks like some weird bug and I guess that the warning
messages

programming error: Improbable offset for stencil: nan staff space
Setting to zero.
continuing, cross fingers

are related to the problem (which remains also in the latest
development version). Notice that this problem has nothing to
do with you use of \RemoveEmptyRhythmicStaffContext, so
if you send a bug report, you can make the example even more
minimal.
