Sub-groups should not contain empty names. To make sure
that is the case, generate tokens even if the string is
empty.
Before the name 'group1..group2' would generate 2 tokens:
'group1' and 'group2'. As such, validateStatName would
not be able to detect it was an invalid name. With this
change three tokens will be generated: 'group1', '',
and 'group2'. The empty string will then trigger the
item->empty() check, which will successfully inform that
such stat name is not valid.
SLICC was breaking this rule with one of its stats by
creating a sub-group (inTransLatHist) whose parent had
an empty name, so it has been fixed.
