fix: add support for args with spaces to MultiMC::messageReceived()

Previously, when the main instance of MultiMC would receive an `import`
or `launch` message from another instance, it would split the message on
each space, and only read the first word of the argument (zip path/URL
or instance ID). This commit fixes that problem by sectioning the
message string instead.
