Merging persisted state and api-state is done wrong

[roman-1983]

Instead of giving priority to the saved state the script currently merges state and api.state() which leads to mixed up ordering.

Example

Default sort order: Column 1, Column 3 DESC User sort order: Column 2 DESC

IS Sort order after merging

• Column 1, Column 3 DESC, Column 2 DESC

Should Sort order after merging

• Column 2 DESC

As the user sort order should have priority.

I will take care of this and send a PR.
