CREATE CONSTRAINT is not supported

[artemgur]

1. CREATE CONSTRAINT queries are highlighted as errors.

Example of query:
CREATE CONSTRAINT FOR (user:User) REQUIRE user.id IS UNIQUE;
Error message:
<any cypher option>, <create index>, <delete>, <reading clause>, BEGIN, CALL, COMMIT, CREATE, DROP, FOREACH, MERGE, REMOVE, RETURN, SET or WITH expected, got 'CREATE'
Screenshot:

2. When I try to execute CREATE CONSTRAINT queries, an error is shown

Query is the same as before.
Error text:
Error occurred: Cypher query text should not be an empty string
Screenshot:

Error details (unfortunately only as screenshot, because the text in "Error details" window can't be copied):

Completely agrees. I often use constraint to build my schemas. I'll try to fix it. What you think @albertoventurini ?
