fails silently when `src/config/database.js` is missing

[lightmare]

Any command, including exp-api -v, exits with 0 status without printing anything when it can't open src/config/database.js.

There are 4 issues:

• exp-api -v shouldn't be looking for any files to begin with

• utils.checkLangAndDB doesn't handle error from missing ./src:
  

  express-api-cli/bin/utils.js

  Line 86 in d39a7ce

  let files = fs.readdirSync('./src/');

• utils.checkLangAndDB attempts to print error from missing ./src/config/database.js without importing chalk:
  

  express-api-cli/bin/utils.js

  Lines 93 to 107 in d39a7ce

  	try {
  	if (config.lang === 'js') {
  	db = await fs.readFile('./src/config/database.js');
  	} else {
  	db = await fs.readFile('./src/config/database.ts');
  	}
  	db = db.toString();
  	} catch (error) {
  	console.log(
  	chalk.yellow(`
  	Database config not detected in src/config.
  	express-api-cli shall assume project default database config uses mongoose. Thank you.
  	`)
  	);
  	}

• all unhandled errors are swallowed:
  

  express-api-cli/bin/generators.js

  Line 175 in d39a7ce

  } catch (error) {}
