Adjust actor autocomplete depending on consortia

[georgiana-b]

Currently the actor autocomplete text is not matched against the start of the name strictly but against the start of any word within the name.
I made this choice to include in results the companies that appear in consortia and thus not at the start of the string. E.g. To match Apple Inc. and Microsoft Inc. when searching for micro.
However, I am not sure how the consortia are represented in the Digiwhist dataset.

• Research if consortia are already split in the new dataset
• If yes match the search string to the start of the actor name strictly.
