Convert HEIC trip and journey covers to JPEG before upload (#1085)

HEIC/HEIF covers coming straight off an iPhone could not be rendered in
the preview or stored as a usable image. Route both cover pickers through
normalizeImageFile, the same conversion the journal entry editor already
uses, so the file becomes a JPEG before it leaves the browser.
