[bisq-network/bisq] UI: Replace java.util.Collections with FXCollections (#4388)

[cd2357]

As per a [JavaFX performance tuning thread](https://wiki.openjdk.java.net/display/OpenJFX/Performance+Tips+and+Tricks), the use of the `FXCollections` API is encouraged when optimizing for performance.

As per the [`FXCollections javadoc`](https://docs.oracle.com/javase/8/javafx/api/javafx/collections/FXCollections.html):

> Utility class that consists of static methods that are 1:1 copies of `java.util.Collections` methods.
>
> The utility methods are here mainly for performance reasons. All methods are optimized in a way that they yield only limited number of notifications. On the other hand, `java.util.Collections` methods might call "modification methods" on an `ObservableList` multiple times, resulting in a number of notifications.

Replace all usages of `java.util.Collections` with `javafx.collections.FXCollections` in the `bisq-desktop` project (the only one where JavaFX is used).
