Test tryExecuteSirenAction

[bonomat]

Problem

Currently, the logic in the class Swap is not tested as much as we want. That means, if an error occurs somewhere in this logic, in the "best" case the client just crashes, in the worst case we would do something which could harm the user (e.g. accidentally overfund, or underfund, etc )

Goal

Be robust and maintain it by reviewing how to make the sdk robust to runtime failures.

Recommendation

Test that tryExecuteSirenAction actually times out.

Note: doLedgerAction is used in e2e test and has very little logic so there is no use testing it more.
Same for fieldValueResolver.
