Nimsuggest triggers a compiler error when import chronos

[nbonfils]

Importing https://github.com/status-im/nim-chronos in a nim file and then running nimsuggest on that file triggers the following error:

Traceback from system (most recent call last)
Error: unhandled exception: ast.nim(1297, 18) `false` tyProxy [AssertionError]

[saem]

I can't replicate this with latest nimsuggest

https://github.com/saem/nim-misc/blob/main/nimsuggest_116_chronos_error/src/main.nim (ignore the nimble cruft)
