Concatenation of a string is not correct.

Steps to reproduce the behavior:

1. Original line:

    self.enqueue_script(handle='bootstrap',
                        path='xxxxxxxxxxxx/js/vendor/bootstrap.bundle'
                             '.min.js',
                        in_footer=True)
   

2. Run Black no arguments

3. Result:

    self.enqueue_script(
        handle="bootstrap",
        path="xxxxxxxxxxxx/js/vendor/bootstrap.bundle" ".min.js",
        in_footer=True,
    )
   

Expected behavior
self.enqueue_script(
handle="bootstrap",
path="esperanzahomes/js/vendor/bootstrap.bundle.min.js",
in_footer=True,
)

Not having a space in the path string.

Environment (please complete the following information):

• Version: black, version 19.10b0
• OS and Python version: Mac OS Catalina. Black installed through brew. Python 2.7.17
