Avoid global pnpm store (paritytech#921)

* Use local pnpm store

* Fix rustfmt toolchain version

* Add troubleshooting note about pnpm store

* Remove old nvmrc

* Build contracts before relayer

The relayer requires the current contracts' compile artifacts to
generate bindings. Without this, changes to the contracts aren't picked
up properly:

For fresh dev environments, the relayer build fails unless we first
compile the contracts. For existing environments, we must manually
ensure that contracts are built before running start-services, or
relayer contract bindings will be out of date.

* Format files with pre-commit hook

* Add postcheckout hook to keep submodules updated

* Revert "Format files with pre-commit hook"

This reverts commit e9b184cdfcd67a1afc551c919b7d28fe855380ea.

* Revert "Fix rustfmt toolchain version"

This reverts commit c603e5451d5e5f99fd36b9ac02b92163cef11cf9.
