Couplers Breaking Changes

[aorgazf]

Dear all,
chevron routine throws the error shown below when trying to run it on qw5q_gold.
It appears the changes introduced by @Jacfomg to support QPU architectures with couplers were not tested on platforms that do not have couplers.

Already fixed on qiboteam/qibolab#623, it's waiting for review to merge.

I tried this branch and it still does not work on qw5q_gold
