Printing the actual error message when Model.set fails

[sezanzeb]

If the function provided via set throws an error, it will hide the error message, which makes it hard to debug.

  column: {
    ...
    set: () => { throw new Error('foo bar') }
  },

before:

Error: Error using Model.set method for model Product property ... (possibly due to the use of instance methods). You should use option ignoreSet: true.
    at node_modules/sequelize-fixtures/lib/loader.js:105:29

after:

Error: Error using Model.set method for model Product property ... (possibly due to the use of instance methods). You should use option ignoreSet: true.
Error: foo bar
