Currently, if the signature's constant part is not defined, a NameError
would be raised.
```
irb(main):001> show_source Foo
(eval):1:in `<top (required)>': uninitialized constant Foo (NameError)
Foo
^^^
from (irb):1:in `<main>'
```
This commit fixes the issue and simplifies the `edit` command's implementation.

* Decouple `edit` command from `show_source`
2 commands should not depend on each other. If `edit` command also needs
to find a source, the source finding logic should be extracted into a
separate class.
* Return nil if is not an actual file path
* Refactor SourceFinder

Given that `show_doc` already supports syntax like `String#gsub`, it
should be able to take it in non-string form too, like `edit` and
`show_source` do. This ensures users can have a consistent syntax on
argument between different commands.
