Fix -resume with fai usage

[LouisLeNezet]

Description of the bug

Using the fai element in the ch_fasta channel hinder the resume of the pipeline.
When used the cached element aren't used and the pipeline recompute the processes and the succeeding ones.

Possibilities:

• Find why
• Remove the fai as it is not directly used (not even sure it really is used in the different processes)

Example: in the test profile the pipeline will not resume the variant calling at the preprocessing of glimpse 1

Command used and terminal output

nextflow run nf-core/phaseimpute -profile singularity,test --outdir results -resume
