[BUGFIX] Use @phpstan-ignore not @phpstan-ignore-next-line (#1591)

`@phpstan-ignore` has the parameter which is the specific warning to ignore.
`@phpstan-ignore-next-line` does not, and will result in suppression of all
warnings for the next line.
`@phpstan-ignore` also only applies to the next line
(or whatever is relevent in context).
