Fix position of wide images on IRC / modern layout (#8667)

* Move declarations related to position from _MImageBody.scss to _EventTile.scss

These declarations should not be defined as default values as position depends on other factors such as layout, etc.

* Move min-height and min-width declarations from _MImageBody.scss to _EventTile.scss

Since min-height and min-width have been specified for bubble layout, the declarations have been expected to be applied to the other layouts.

* Apply 'justify-content: center' to bubble layout only

'justify-content: center' was added for the bubble layout with 1436f23. It should not be applied to the other layouts.

In order to prevent an issue related to cascading from happening, 'justify-content: flex-start' is explicitly specified.
