On latest MM Dev builds, VariableIsSet Condition does not work.

Title. When tested, the condition does not work.

Example:

test-conditions-cast:
  Skills:
  - setvariable{var=caster.somevar;value="hello"} @self
  - skill{s=test-conditiontest-exec} @self
  
test-conditions-exec:
  Conditions:
  - varisset{name=caster.somevar} orelsecast test-conditions-notset
 # - variableisset{variable=caster.somevar} true
 # - variableisset{variable=caster.somevar} false
  Skills:
  - message{m="Variable set, <caster.var.somevar>"}

test-conditions-notset:
  Skills:
  - message{m="Variable not set, <caster.var.somevar>"}

As shown above, the variable somevar is set to "hello".

However, when tested, neither the skill test-conditions-exec nor test-conditions-notset run. When testing with true/false, neither returns a result.

I believe this issue appeared around the time when nested placeholders were implemented.

A fix would be appreciated.
