fix multi measure rest: add key and time signature. add Function Test. MultiRestMeasure extends VexFlowMeasure (#506)

fixed key and time signature missing in multi rest measures (e.g. first measure in function test),
methods were falsely overridden.

refactor VexFlowMultiRestMeasure: now extends VexFlowMeasure instead of GraphicalMeasure, so it's easier
to use the methods in VexFlowMeasure.

add OSMD Function Test - Multiple Rest Measures

fix end barline in multi rest measures not detected correctly (e.g. final barline, see function test)
