dba4cfa791 Initialized the sublist for benchmark tests only when needed 
This saves a lot of memory and init time when running non benchmark
tests in race mode.

668229fc1d [FIXED] RACE between sublist remove and go through match results 
This would manifest for instance when server tries to send messages
to queue subscribers and a subscription is unsubsribed at the same
time.

Resolves #640

8ec1f77ac8 [FIXED] Sublist Insert and Remove with wildcard characters in literals 
This is similar to #561 where `*` and `>` characters appear in tokens
as literals, not wilcards.
Both Insert() and Remove() were checking that the first character
was `*` or `>` and consider it a wildcard node. This is wrong. Any
token that is more than 1 character long must be treated as a literal.
Only for token of size one should we check if the character is `*`
or `>`.
Added a test case for Insert and Remove with subject like `foo.*-`
or `foo.>-`.

515779ae0b [FIXED] Use of * and > in subjects as literals 
The issue was that a subject such as `foo.bar,*,>` would be
inserted to the cache as is, but when trying to remove from the
cache, calling matchLiteral() with the above subject in the cache
against the same subject would return false. This is because
matchLiteral would treat those characters as wildcards token.

Note that the sublist itself splits subjects on the `.` separator
and seem not bothered by such subject (would have `foo` and `bar,*,>`
tokens). Also, note that IsValidSubject() and IsValidLiteralSubject()
properly checked that the characters `*` and `>` are treated
as wildcards only if they are tokens on their own.

Resolves #558
