Space logos accessible even without read permissions on the space

User macros are handy to create a list of spaces, including spaces a user may not have access to.

Good user experience requires logos to be displayed as well.

However, $spaceManager.getLogoForSpace($!space.key).getDownloadPath() requires the user to have access to the space. Hence the list of spaces doesn't look good to all users.

Please make the space logo's accessible to users having no read access to the space.
