Make template lookup more confident

[julianrubisch]

By trying to get a template matching self.class.name.underscore first.

This fixes inline rendered views (i.e., without a top-level view file)

That method is actually looking for the template that rendered the component, not the template that the component renders.

It's the differeniate between different component instances

# index.html.erb

<%= render MyComponent.new %> # index.html.erb:1 <- unique identifier
<% render MyComponent.new %> # index.html.erb:2 <- unique identifier

Hmmm so I need to approach that differently.

Any idea what could work?

Providing the key manually through collection_key is the only solution I've come up with so far. It's something I wnated to solve for Ilex, but I haven't had any good thoughts so far.

My knee-jerk reaction is to just always use second call in the call stack, because that's always going to be what's rendering the component, but I seem to recall trying that initially and running into problems. It might have had something to do with debuggers not playing nicely...

Definitely something to check
