Param defaults are override to null if params.name = is found in main.nf

[mirpedrol]

Description of the bug

When we obtain the configuration defaults we parse the main.nf to find params declared there.

tools/nf_core/utils.py

Line 291 in 9eac5e9

match = re.match(r"^\s*(params\.[a-zA-Z0-9_]+)\s*=", line)

In some cases this regex matches wrong lines and overrides the real defaults to null.
