localrepo: set heads and branchheads to be closed=False by default

without explicitly setting the closed argument the heads(...) and
branchheads(...) functions will not return closed heads

this will cause 'hg merge' to have better behavior in the presence of
a branch that has closed heads when an explicit rev is not given
