fix: call execPostHooks on internalTransaction

[BasKiers]

I noticed that when using an internalTransaction (the default behaviour when no transaction is given) for the update method the transaction.execPostHooks function is never called.
I fixed this by adding a line to the internalTransaction check and appending errors to entity[ERR_HOOKS]

I initially tried to add a test but found it non-trivial to mock the transaction used in the update method.

Hi,

Thanks a lot for this! I must say that I am surprised to not find any reference to the symbol gstore.ERR_HOOKS in the code... I might have got lost in a refactor.

For the test, I would probably have gone the "integration" path as it seems indeed very complex to stub the internal transaction. For that, you need to launch an instance of Redis (on the default port) and then in parallel launch the local datastore with yarn local-datastore or npm run local-datastore. Then, to execute those tests it is

yarn test --int
# or
npm run test -- --int

If it's too complex, don't worry and let me know. We can merge this PR and I will add the tests in a second pass.

Hi,

I am not planning to write tests for this PR due to the added complexity of creating integration tests.

HI,
Sorry for the delay, I was out for a week. Ok no worries, I will merge the PR and see if I can add some tests.
Thanks again for fixing this!
