// Test the various ways opening a cookie database can fail in a synchronous
// (i.e. immediate) manner, and that the database is renamed and recreated
// under each circumstance. These circumstances are, in no particular order:
//
// 1) A corrupt database, such that opening the connection fails.
// 2) The 'moz_cookies' table doesn't exist.
// 3) Not all of the expected columns exist, and statement creation fails when:
// a) The schema version is larger than the current version.
// b) The schema version is less than or equal to the current version.
// 4) Migration fails. This will have different modes depending on the initial
// version:
// a) Schema 1: the 'lastAccessed' column already exists.
// b) Schema 2: the 'baseDomain' column already exists; or 'baseDomain'
// cannot be computed for a particular host.
// c) Schema 3: the 'creationTime' column already exists; or the
// 'moz_uniqueid' index already exists.
