defaultMeta ignored when using logger.log function but not in logger[level] functions

Please tell us about your environment:

• winston version?
  • winston@2
  • winston@3 3.2.1
• node -v outputs: v13.5.0
• Operating System? (Windows, macOS, or Linux) macOS
• Language? (all | TypeScript X.X | ES6/7 | ES5 | Dart) ES6/7

What is the problem?

When calling the function logger.log('debug', 'message') it seems to completely ignore defaultMeta, but calling functions like logger.debug does not

My createLogger

const logger = winston.createLogger({
  level: "debug",
  defaultMeta: { id: 'APP' },
  format: winston.format.combine(
    winston.format.colorize(),
    winston.format.timestamp({
      format: "YYYY-MM-DD h:mm:ss:SSS"
    }),
    winston.format.printf(
      info => `${info.timestamp} ${info.level}: [${info.id}] ${info.message}`
    )
  ),
  transports: [new winston.transports.Console()]
});

What do you expect to happen instead?

Given my createLogger setup above I expect both

logger.info("This is my info")

AND

logger.log("info", "This is my info")

to both print out this to the console:

2020-02-04 11:30:34:313 info: [APP] This is my info

However the latter (logger.log) prints this

2020-02-04 11:30:34:307 info: [undefined] Initializing web sockets

Still the same on 3.3.3

Same happening with profiling, the logger.profile() method ignores defaultMeta.

So is this actually an issue or the expected behavior?
