Dialog improvements

[berezh]

Currently, it opens/closes with state flag within a component.
Disadvantages:

• need to create additional flag in redux store to handle case the form successfully submitted, subscribe it and if it true - close the dialog. This hack makes app complicated and increases possibility to get a but.
• dialog can be opened/closed only from specific component by subscribing state flag

To resolve above need to move opeding/closing to redux action.
