[EIP]: Saga: wrong option property interpretation

[mmelko]

Describe the Bug

The main problem here is probably that in the catalog option is defined as a list of ExpressionProperty. In the form is a combination of ExressionProperty and Expression, which might lead also to incorrect serialisation to yaml.

Steps to Reproduce the Bug or Issue

1. create a route with the Saga EIP
2. try to add a option with random key

3. If both expression fields are filled it leads to wrong serialisation to yaml.
