Files with corresponding tmpl version not ignored when using subdirectory

[cbrown1234]

Describe the problem

When your template is in a subdirectory, it doesn't automatically ignore the files that have a .tmpl version (feature added here: #99).

Template

template.zip

To Reproduce

1. copier copy . /tmp/example
2. Entry project name
3. See conflict

(I have also included a test in the MR with the fix I will raise soon)

Logs

❯ copier copy . /tmp/example
No git tags found in template; using HEAD as ref
🎤 What is your project name?
   jdsakl

Copying from template version 0.0.0.post9.dev0+16f462d
    create  README.md
    create  .jdsakl-answers.yml
  conflict  README.md
 Overwrite README.md? [Y/n] y

Expected behavior

It should not show a conflict and pause for an overwrite
