Bug Description

Previously, with SwiftLint 0.59.1, this code does not trigger a line_length warning when ignores_function_declarations: true:

public class FileDataStore {
    public init(persistenceService: PersistenceService, syncService: SyncService, notificationService: NotificationService) throws {
        // ...
    }

    public func doSomething(persistenceService: PersistenceService, syncService: SyncService, notificationService: NotificationService) throws {
        // ...
    }
}

$ swiftlint Modules/Sources/Stores/DataStore/FileDataStore/FileDataStore.swift
Linting Swift files at paths Modules/Sources/Stores/DataStore/FileDataStore/FileDataStore.swift
Linting 'FileDataStore.swift' (1/1)
Done linting! Found 0 violations, 0 serious in 1 file.

After upgrading to SwiftLint 0.61.0, the line_length rule (still with ignores_function_declarations: true) now warns about a violation on the public init line, but not on the public func line.
