pgAdmin 4 commit: Fixed following issues for query tool after react por

Fixed following issues for query tool after react porting:

1) Add New Server Connection > Server options keep loading(For empty Server group).
2) After clicking indent/Unindent(for all operations) for large query option left as it is till operation completes
3) Check sign beside options in Execute Option/Copy Header is little bit big
4) In explain > Analysis tab does not show ROWS column
5) In explain > Explain > analysis previous explain output is NOT cleared. New rows are appended. Same applies to the statistics tab.
6) Update new query tool connection tool tip. Fixes #7289
7) Explain-Analyze > Loops column is empty.
8) Explain-Analyze with Verbose & Costs > in ROW X columns upward arrows are missing.
9) Explain-Analyze with all option checked > background colors are missing for timing.
10) Explain-Analyze > Additional bullet is added before Hash Cond.
11) Browser Tree > Filtered rows icon is not working.
12) Create table with timestamp and default value as function now() > Add new row > Enter mandatory columns except column where default value is function(now()) > Click Save > New row added but column with default value has value [default]. not updated to actual value. / Default values are not considered for any column while adding a new entry.
13) Disable execute options in View/Edit data.
14) The Boolean column always shows null.
15) In Query history Remove & Remove all buttons are stuck to each other.
16) On Remove all, the right panel is empty.
17) Create a column with boolean[]/ text[], Try to add a new entry from data grid, enter “” quotes > Click Ok > Now try edit cell > You can not change value.
18) In query history - Select queries are suffixed by ’Save Data’ icon
19) Edit any table with PK > Try to insert duplicate PK > Error thrown > Correct pK value > Still old error shown > Not able to add new entry (This works when focus is moved from edited cell)
20) Clicking arrows after opening dropdown options, does not collapse dropdown.
