Ignoring repeated constraints

[dmikhalin]

Problem to Solve

It seems that current typeql-rust ignores repeated constraints, but we have this scenario in BDD: https://github.com/vaticle/typedb-behaviour/blob/7675fefe3f3b555ce9db558fda27d5ac2314fb17/typeql/language/define.feature#L1263

Proposed Solution

Fix typeql-rust parser behaviour to make it consistent with java parser. This scenario is temporarily ignored.
