Replace TryDequeue with Count == 0 check

[anders9ustafsson]

This PR addresses a limitation in .NET Standard 2.0, where the method Queue.TryDequeue is not implemented. I have refactored the associated code to instead check if the queue is empty (Queue.Count == 0), which should mimic the behavior of the TryDequeue method.

This fix is only relevant in case it is decided to target .NET Standard 2.0, see discussion in #3503 .

Hi @anders9ustafsson , maybe it's better to check term.Count property instead of try-catch. Seems, it exists in .Net standard?

[anders9ustafsson]

@CADBIMDeveloper Personally, I would say that the changes I propose in the PR are straightforward modifications of the original code, and thus preferable.

Howeer, if you are concerned with the usage of try-catch, don't hesitate to provide an alternative solution to the issue. Perhaps in a separate PR?

@anders9ustafsson I was just interested in motivation of using try-catch here. I thought I missed something about queue implementation in .Net and it was not safe to check Count property here for some reason I was not aware of.

[anders9ustafsson]

@CADBIMDeveloper I will give some thought to your suggestion, you are probably right that it is a less intrusive way to use Queue.Count instead.

[anders9ustafsson]

@CADBIMDeveloper In the end, I found your suggestion more appealing, so I have updated the pull request according to your recommendation. Many thanks!
