Make forceExclude work with directly specified files

[jimmya]

It seemed that --force-exclude didn't work when providing files directly.
.swiftlint.yml:

excluded:
  - ./**/*Test*

Directory contents:

 |-.swiftlint.yml
 |-Source
 | |-FooBar.swift
 | |-FooTest.swift
 | |-Foo.swift

When specifying a file that matches this excluded list:

➜ swiftlint --config .swiftlint.yml --force-exclude Source/FooTest.swift
Linting Swift files at paths Source/FooTest.swift
Linting 'Foo.swift' (1/2)
Linting 'FooBar.swift' (2/2)

Because it fell through the if statement it started linting all included files.

When specifying a file that doesn't match:

➜ swiftlint --config .swiftlint.yml --force-exclude Source/Foo.swift    
Linting Swift files at paths Source/Foo.swift
Linting 'Foo.swift' (1/1)

Expected result:

➜ swiftlint --config .swiftlint.yml --force-exclude Source/FooTest.swift                
Linting Swift files at paths Source/FooTest.swift
Error: No lintable files found at paths: 'Source/FooTest.swift'

This PR makes sure that this excluded list is taken into account when specifying the --force-exclude flag.
