Add space at the end of the modeline diagnostics and actions (#2100)

lsp-mode adds modeline diagnostics and code actions to the beginning
of the global-mode-string. This means that if we want every
global-mode-string construct to look correctly, we need to append, and
not prepend, a space after our mode line string.
