0.13: [Bug]: Variable referencing CLI parameter can't be resolved when running `dev` command

[vvagaytsev]

Garden Bonsai (0.13) Bug

Current behavior

If a project-level variable definition references a command-line parameter via ${command.params.*} (e.g. ${command.params.env}), the variable can't be resolved when starting garden dev command, and the error is printed:

Failed to resolve project configuration.

Unable to load Garden project found at ~/Repositories/repros/split-string-index-access: Error: Invalid template string (${split(command.params.env, ".")}) at path variables.env: Error validating argument 'string' for split helper function:

value must be a string

The dev console starts, the process doesn't crash.

Expected behavior

The variable should be resolved.

Reproducible example

See #6150.
