There was a edge case with the declaration of the `lsp` layer in `layers.el`
files.
The `hy` layer depends on the `python` layer which in turn depends on the `lsp`
layer if and only if the `python-backend` layer variable is set to `lsp`.
When the `hy` layer was declared first then it declares the `python` layer
without its layer variables, thus the `lsp` layer was not declared because the
`python-backend` variable was not set.
The fix is to gather all the layer dependencies and resolve them only after all
the used layers have been declared.
* new function `configuration-layer/declare-layer-dependencies`
* replace all calls to `configuration-layer/declare-layer` by the new function
except for distribution layers (we declare layer dependencies right away in
distribution layers)
problem:
some layer packages lists have the open and closing parentheses on the same line
as the first and last listed package, but most seem to have them on a separate
lines.
solution:
put the open and close parentheses on separate lines, except for lists with only
a single package, they are written on the same line as the variable name and
parentheses.
fix the lists indentation
- First remove elixir's layer project prefix, since it was used only for
one binding which would be better suited in tests prefix
- Move `alchemist-project-find-test` to test prefix
- Add `phoenix` prefix and declare bindings
