load_dot_env called twice in `pipenv shell`

Issue description

When executing a pipenv shell the internal function load_dot_env is called in both the cli and shell functions.

Note that in the shell call, load_dot_env is not passed the state.quiet argument.

Expected result

The function is called only once in the cli function with the quiet option.

Actual result

$ pipenv shell
Loading .env environment variables...
Loading .env environment variables...
Launching subshell in virtual environment...
...

$ pipenv --quiet shell
Loading .env environment variables...
Launching subshell in virtual environment...
...

Steps to replicate

No Pipfile necessary -- just run pipenv.

$ pipenv shell
Loading .env environment variables...
Launching subshell in virtual environment...
...

$ pipenv --quiet shell
Launching subshell in virtual environment...
...

$ pipenv --support
