fixing wildcard expansion in clusters bug

[tom-brekke]

Following from #869

I used nf-core modules update vsearch/cluster to update the vsearch/cluster module
the update is a fix for the wildcard expansion that has been vetted by nf-core/modules and just needs integrating into ampliseq.

Thanks!
It seems to me that you made the changes in the master branch though, that is not optimal. Optimal would be the dev branch, because the dev branch is the one with the most up to date code and the PR here has therefore weird history. Would you be willing to do it with the dev branch?
Apart from this I just have one other note: the CHANGELOG.md also should be updated with the change.

Sorry about that - sorting it now.
when I cloned the ampliseq repo I only grabbed the master branch. Had to delete my fork and re-clone.
