Fix chrome crashing in mash_session.

Fix chrome crashing in mash_session.

The chrome browser process would crash upon starting in mash_session.
This resulted from the MojoShellConnection being initialized after it
was used for the first time. Move the initialization of
MojoShellConnection to immediately before it's first used to fix crash.
