Fix unpredictable state data behaviour

[IlinaGergova]

Background

Some of the properties saved in the state are sets which lead to unpredictable behaviour because sets cannot deserialize.

Aim

To use arrays instead of sets.

Implementation

Change datasets state and gene profiles state to use arrays.
