bug in sqlite3 driver.

[starwing]

at line 23 of sqlite.js:

        // on Windows, paths have a drive letter which is parsed by
        // url.parse() as the hostname. If host is defined, assume
        // it's the drive letter and add ":"
        if (process.platform == "win32" && config.host.match(/^[a-z]$/i)) {

if we use a opts table instead of URL, the config.host may undefined, so have a check is required.

a change to

        if (process.platform == "win32" && config.host && config.host.match(/^[a-z]$/i)) {

avoid this issue.
