WrappedDataWatcher#hasIndex too slow because of try/catch

[MeGysssTaa]

Describe the bug
The current implementation of WrappedDataWatcher#hasIndex makes use of method public Object getObject(WrappedDataWatcher.WrappedDataWatcherObject object). In order for this method to return null, or, in other words, in order for hasIndex to return false, a NullPointerException or an InvocationTargetException must be thrown and handled:

(see screenshot 1)

This solution is slow in scenarios where hasIndex is called very often (for example, when using a custom data watcher to create cross-compatible packet NPCs):

(see screenshot 2)

To Reproduce
Steps to reproduce the behavior:

1. Use method hasIndex of WrappedDataWatcher often enough, e.g. in a custom data watcher for cross-compatible packet NPCs.
2. Create a Java Flight Recording.
3. Enjoy a ton of NullPointerExceptions and even more InvocationTargetExceptions in the exceptions tab.

Expected behavior
I would really appreciate it if this method was faster and avoided use of any try/catch statements and exception handlers, so that it may be called very frequently without negative performance consequences.
